Claims (14)
- Procédé permettant de changer automatiquement un mode de fonctionnement d'un moteur à combustion interne entre un mode économique et un mode de performance comprenant les étapes suivantes :la détermination d'un rapport carburant-air actuel auquel le moteur fonctionne ; la comparaison du rapport carburant-air actuel à une limite de rapport carburant-air prédéterminée ;la détermination d'une durée pendant laquelle le rapport carburant-air actuel est inférieur à la limite de rapport carburant-air et la comparaison de la durée à une valeur seuil de temps d'attente prédéterminée ;la fourniture d'un compte basé sur une différence entre le rapport carburant-air actuel et la limite de rapport carburant-air lorsque le moteur fonctionne à un rapport carburant-air actuel qui est inférieur à la limite de rapport carburant-air et la comparaison du compte avec une valeur seuil d'intensité ;le changement du mode de fonctionnement du moteur du mode de performance au mode économique lorsque la durée et le compte dépassent la valeur seuil de temps d'attente et la valeur seuil d'intensité respectivement ; etle changement du mode de fonctionnement du moteur du mode économique au mode de performance lorsque le rapport carburant-air actuel atteint ou dépasse la limite de rapport carburant-air.
- Procédé permettant de changer automatiquement un mode de fonctionnement d'un moteur à combustion interne entre un mode économique et un mode de performance comprenant les étapes suivantes :la détermination d'un rapport air-carburant actuel auquel le moteur fonctionne, la comparaison du rapport air-carburant actuel à une limite de rapport air-carburant prédéterminée ;la détermination d'une durée pendant laquelle le rapport air-carburant actuel est supérieur à la limite de rapport air-carburant et la comparaison de la durée à une valeur seuil de temps d'attente prédéterminée ;la fourniture d'un compte sur la base d'une différence entre le rapport air-carburant actuel et la limite de rapport air-carburant lorsque le moteur fonctionne à un rapport air-carburant actuel qui est au-dessus de la limite de rapport air-carburant et la comparaison du compte avec une valeur seuil d'intensité ;le changement du mode de fonctionnement du moteur du mode de performance au mode économique lorsque la durée et le compte dépassent la valeur seuil de temps d'attente et la valeur seuil d'intensité respectivement ; etle changement du mode de fonctionnement du moteur du mode économique au mode de performance lorsque le rapport carburant-air actuel atteint ou descend en dessous de la limite de rapport air-carburant.
- Procédé selon la revendication 1 ou la revendication 2, dans lequel la durée et le compte sont remis à zéro lorsque le mode de fonctionnement du moteur change du mode économique au mode de performance.
- Procédé selon la revendication 1 ou la revendication 2, dans lequel la durée et le compte sont mis à zéro au démarrage du moteur et le changement du mode de performance au mode économique est interdit jusqu'à ce que le moteur ait satisfait à des vérifications de condition de démarrage prédéterminées.
- Procédé selon l'une quelconque des revendications précédentes, dans lequel l'étape de fourniture du compte comprend la détermination de la différence de manière répétée de telle sorte que le compte soit cumulatif.
- Procédé selon la revendication 5, dans lequel la détermination de la différence est effectuée à un intervalle de temps prédéterminé constant.
- Procédé selon l'une quelconque des revendications précédentes, comprenant en outre l'exécution de vérifications de condition de démarrage et, dans le cas où une vérification de condition de démarrage échoue, le maintien du mode de fonctionnement du moteur dans le mode de performance.
- Système de moteur comprenant :un moteur à combustion interne ayant au moins deux modes de fonctionnement comprenant un mode économique et un mode de performance ;au moins un capteur fournissant au moins un signal de sortie selon au moins un paramètre de fonctionnement du moteur ; etun dispositif de commande configuré pour recevoir ledit au moins un signal de sortie de l'au moins un capteur et pour déterminer le rapport carburant-air actuel du moteur à partir dudit au moins un signal de sortie ;dans lequel une limite de rapport carburant-air prédéterminée, un seuil de temps d'attente prédéterminé et un seuil d'intensité prédéterminé sont stockés dans le dispositif de commande et le dispositif de commande est programmé pour changer le mode de fonctionnement du moteur entre le mode économique et le mode de performance selon le procédé selon l'une quelconque des revendications 1 ou 3 à 7, ne dépendant pas de la revendication 2.
- Système de moteur selon la revendication 8, dans lequel l'au moins un capteur comprend un capteur de rapport carburant-air configuré pour fournir le rapport carburant-air du moteur.
- Système de moteur comprenant :un moteur à combustion interne ayant au moins deux modes de fonctionnement comprenant un mode économique et un mode de performance ;au moins un capteur fournissant au moins un signal de sortie selon au moins un paramètre de fonctionnement du moteur ; etun dispositif de commande configuré pour recevoir ledit au moins un signal de sortie de l'au moins un capteur et pour déterminer le rapport air-carburant actuel du moteur à partir dudit au moins un signal de sortie ;dans lequel une limite de rapport air-carburant prédéterminée, un seuil de temps d'attente prédéterminé et un seuil d'intensité prédéterminé sont stockés dans le dispositif de commande et le dispositif de commande est programmé pour changer le mode de fonctionnement du moteur entre le mode économique et le mode de performance selon le procédé selon l'une quelconque des revendications 2 ou 3 à 7, ne dépendant pas de la revendication 1.
- Système de moteur selon la revendication 10, dans lequel l'au moins un capteur comprend un capteur de rapport air-carburant configuré pour fournir le rapport air-carburant du moteur.
- Système de moteur selon l'une quelconque des revendications 8 à 11, dans lequel l'au moins un capteur comprend un capteur d'oxygène, dans lequel le paramètre de fonctionnement du moteur comprend une mesure d'oxygène à l'intérieur du moteur.
- Système de moteur selon l'une quelconque des revendications 8 à 12, comprenant en outre une unité de commande de moteur.
